does a 1-2" lift based on spacers on the air-suspension and front t-bars exist?

The front of the truck can be raised by simply cranking the torison bar bolts... at the expense of ride quality. So says my dealer. My question is can i put a spacer in wherever the bolts would raise the truck and get an inch or 2 with no ride quality penalty?

I am not interested in a full-blown lift.

 

We have a Truxxx kit that only runs 399.99 and lifts the front end up 2 to 3 inches and doesnt affect your ride.
I have installed a lot of these and i have never hav a problem with them.
